Central London takes less time to get portals accepted than Greater London
I live in Zone 3 in London. Most of my hyper local portals are still somewhere in system after 1 month. There's a bunch of 4/5* stuff in there.
I'm in Central London (specifically Kings Cross) a couple times a week and i figured i would check out how long review times were there. I got a portal accepted this morning after only 23 days.
I have 38 portals from Zone 3 that are older than that. Some as old as 2 months. I'll be lucky if I hear back from all of them within the next 23 days let alone get them fully reviewed in that time.
You can usually find me moaning about full review times, and I can wait, but this takes more than just the biscuit.
